Okay, so I am not a professional reviewer by any means, but I am sitting here listening to my Fostex TH-X00's right now and I am extremely happy with them. I have owned a few other headphones; Beyer DT770, Sen HD595, Sen Momentum over ears and HE560s, with my HifiMan HE560's being my favorite of them all. The 560 just sounds great out of everything I have. Everything being an iPhone (maybe not so great out of the phone), iPad, Schitt Modi Stack and a Woo Audio WA7 Fireflies with the tube power supply.
Well I opened up my MassDrop box and they are pretty. The cups are not perfect, a few blemishes and a little wood imperfection. I think they just add character so I am not going to worry about that.
So I warm up my WA7, it has the SOVTEC tubes in it right now. I find they are more musical with the HE560 than the EH gold pins. While they are warming up I try them out of my iPhone, I heard they were easy to power so why not. Not bad, but the tubes should be warm by now.
I plug in the head phones and start playing Rebecca Pidgeon's Spanish Harlem. The bass comes in and its bloated and muddy!! And this is an acoustic stand up bass. Oh no.. I play a few other songs across different genres and I am pretty disappointed. My ears are used to my HE560's that take everything you throw at them and are never more than honest with the music. Everything is incoherent and muddy. Time to test some serious bass so here comes Techmaster P.E.B. with Bassgasm. Okay these cans have some seriously strong bass, but its not good bass. Everything sounds jumbled. I try my iPhone again and its def better than the WA7. I read that tubes might not be that great with these cans, but this bad? while on my iPhone they are good but not much above average. I try the voltage setting on the WA7, not much change.
Then I remember that I had the monoprice adapter and the WA7 has a dedicated IEM input. I plug them into that and its a whole new ballgame. Everything is tighter and more coherent. I have to turn the amp up much higher for the same volume but wow, these are sounding seriously nice. The bass is tight and deep. It slams with dance music. Totally different sport than my HE560's so I don't feel there is any reason to compare them directly since they compliment each other so perfectly. The highs are a little recessed it seems, so lets play with the voltage switch... Ok, so I have never heard a difference when flipping that switch before. I was starting to think it was just decorative. I happen to be listening to a Jazz drum solo at the time, and when that switch snapped into place, the sparkle of the high hats and cymbals jumped up into this wonderful place. Just WOW!
I plugged in my Schitt Modi stack and gave them a whirl on there as well. They are amazing, but I have to give it to the WA7 through the IEM jack with the voltage switch set to high. Just amazing out of that set up. I have to keep switching back and forth between the 1/4 inch and the IEM output just to make sure that I am not fooling myself. When I am plugged into the IEM jack I keep switching between low and high voltage as well. Def not in my head.
I have never heard any of the Dennon's or the older brothers to these, the TH-600 and 800, so I cannot comment on how they compare. I just know that I am more than happy with these right now and that IEM output on my WA7 is finally getting used, so there is that. Worth 400 dollars? Absolutely. They are just so much fun.

PixelPusher21The WA7 has 36 ohms output impedance on the 1/4" jack. Pretty low for a tube amp from the ones I have checked out, but not even close to what you want for these headphones. You want something under 3ohms output impedance. Having 36 ohms means it is higher than your headphones and has a 1:1.44 ratio, you want an 8:1 ratio for output impedance to headphones. Most likely the special IEM output goes through some other circuitry inside your WA7 and has lower output impedance which is why the headphones suddenly sound so much more tight. That looseness and muddy bass is exactly what happens when your output impedance is too high to properly control the headphone. I'm glad you found a workaround. And it is also good that now you know exactly what it sounds like when hardware is matched badly. Good experience from the real world usage scenario :)
EDIT: seems the WA7 has about 22 ohms output impedance on the 1/8" jack. Still high compared to what you want but at least you got over a 1:1 ratio (barely). lol

EniGmA1987Makes me wonder about other people saying the bass is loose. I have the Schitt Modi Stack too, and while they sound really nice out of those, the IEM jack really makes these headphones fun to listen too. Makes it so that I have three headphones in one since I can also use them on my iPad and iPone without any amp at all. Fun Fun Fun drom the WA7, more analytical bit still more on the fun side with the Schitt Modi, and just pleasurable out of the I devices (they are great with garage band and my guitar plugged in to Bias)

PixelPusher21Interesting that you had an opposite reaction with the included Monoprice adapter. I tried using it on my Nexus 6p (no amp) and the sound was so far away and there was background clicking. So I swapped the adapter out with another I have, which gave a satisfying click to let me know the adapter was securely on and it made all the difference in the world. Now to see how they sound with my favorite little Aune T1.
As an aside -- I've owned the D2000s with the wooden 7000 cups and simple Lawton mod, but truly these TH-X00s sound much better to my ears. I wish I was more of an audiophile so I could describe more accurately...but out of the box the mids are clearer, the bass is still lovely (maybe not quite as impactful?), and the treble is just right without fatiguing my treble-sensitive ears. Overall these headphones are just right for home listening. My music tastes are generally rock/indie rock/classic rock/folk/acoustic/country. I was worried about the pads and their shape, but they are perfectly comfortable and fit just fine for my normal/medium ears.

mayorblurpsI was not using it into a phone, I have to use a different adaptor for my phone since that plug won't push in far enough with my case. I have a small extension cable that I use for that. 1/4 into the 1/8in adaptor to the small extension cable.
